\begin{equation*}\frac{Girl}{Guy} \to \frac{Girl}{lonely} \frac{Guy}{Mistress} \to Divorce \frac{Guy}{Tissues+Pr0n}

Also notice the use of bold.  All variables which are bold are vectors, and all variables which are not bold are scalars, but not all bold things are vectors, take, for example '''this''' word.\end{equation*}
